New research has revealed that nearly 75 percent of iPhones and iPads have updated to iOS 7, which is the latest version of Apple's mobile operating system.

Advertising company Chitika, carried out the research for iOS adoption and generated the numbers by measuring millions of ad impressions generated in their advertising network. According to the research, 75 percent of iPhones and 65 percent of iPads have been updated to iOS 7 since its launch.

The latest analysis again underscores that iPhone users, and iPad users to a lesser extent, update at extremely high rates, acting as a distinctive selling point when it comes to attracting application and mobile Web developers to the platform.

Chitika also expects the gap between iOS 6 and iOS 7 devices to widen as a number of legacy devices have been excluded from the update as compared to iOS 6 which had nearly 90% adoption in its lifetime.
